α/β-Peptide analogues of fragments derived from Bim BH3, sPLA2, and GP33 used in this study. (a) Structures of an α-amino acid residue and the homologous β³-amino acid residue. (b) Sequences of Bim BH3-derived peptides. The conventional single-letter code is used to indicate α residue identity. Blue dots indicate sites of α → β³ replacement; each β³ residue bears the side chain of the α-residue indicated by the letter. (c) Sequences sPLA2-derived peptides. Peptide ent-4a is the enantiomer of 4a. (d) Sequences GP33-derived peptides.
